In an interview with New York radio station Z100, Spears was asked if she planned to tour.
"Oh definitely, next year," she said, adding the tour would probably take her "around the world."
That would mark her first major concert tour since 2004.
Last year, Spears performed in a handful of club shows in southern California under the name the M+M`s but did not go on the road to promote her last album, Blackout, which had a good chart debut in November 2007 but faded quickly.
After more than a year of making headlines for shaving her head, attacking paparazzi with an umbrella and two admissions to psychiatric hospital units, Spears, 26, is preparing for a comeback.
Her last live public performance was a much-ridiculed rendition of Gimme More at the MTV Video Music Awards a year ago.
The singer`s latest single, Womanizer, was released on Friday and is the first single off Circus, which will be released on December 2 - her 27th birthday. She told Z100 she spent six months working on the album.
Spears has been on the mend since her father took control of her business affairs in February. She won three awards for her song Piece of Me at this year`s MTV video music awards.
Before her life spiraled out of control, Spears was an international pop phenomenon and one of the best-selling artists of the last decade with sales of more than 62 million albums.
